2002 Chevy Silverado squeaking from engine when motor is cold just started this

So about a weak ago i noticed a squeaking noise coming from the engine or hood it is coming from one of the belts or pullys it sounded like it was from the ac belt tensioner so i replaced the pully on the tensioner and also replaced the idler pully thing this was it but fired her back up and started squeaking again i checked the belts they look feel fine no cracks or anything but im not sure how old they are could they be causing the problem ? im not sure how old they are or when the last time they were replaced but they dont look to bad right now thats why i started out with the pullys any information helps if i cant figure it out ill have to go back to the dealer ship and get it checked out it sounds like the sound is coming from right where the ac belt is when i put water on the belt it stops squeaking for a little while then comes back until engine is warm then you can almost not here it at all or there is nothing there when the engine gets warm any ideas help dont think its a bad alternator pully either because the noise is not any where close to this pully

SOURCE: My 1998 Caravan has a bad squeek in the belt

Without the belt do all the pulleys turn easy. Power steering, water pump, alternator, and tensioner pulley. There is probably only one way the belt will stay on but make sure you have the smooth side to the smooth pulley and the grooved side to the grooved pulleys. See if any of the pulleys have and wiggle in them.

the ol used has been inappropriate for the weather conditions and the engine bearings have been starved of lubricant. From your description , it appears that there is bearing failure in the engine.

Have a 2002 Hyundai Elantra that makes creaking noise in stearing wheel , not so much when cold but definitely when it is hot


Sometimes the boot or the rubber at the base of the steering column will make that type of noise. To help eliminate it, rule it out or identify it spray some silicone spray on both sides of the boot/rubber inside and outside.

I get a clunking noise from the front of my truck when I cold start it and only for a few min as is warms up then it goes away. This started in cold weather 35-60F. I have a chevy silverado 2001 1500...


this engine has forged pistons whitch expand more than hyper-u-tec-tic pistons when heated . this is normal for this engine . my brother has a chevy silverado 2001 1500 4.8Lwith 650,000 kms and he said his made that noise when it was brand new and the dealer said this is normal. the truck still runs like new with lots of power and it still makes that noise before it reaches operating temp then goes away.My brother uses lucas oil treatment and it helps quiet the knock a little when cold.
